If non-autistic people are constantly misunderstanding autistic people maybe there should be some meeting in the middle instead of broadly declaring neurodivergent people to be the problem.
They did not in any way “declare neuro divergent people to be the problem.”
If you go around your day and are constantly being misheard, it’s more likely that you’re mumbling than it is that every other person just has bad hearing.
Their comments are making broad statements about autistic people and putting the onus of understanding solely on them, when communication is a two way street.
“Everyone” doesn’t have trouble understanding autistic people; other autistic people are more able to socialize with autistic people than neurotypical people are. Being a minority just means the people who are able to socialize well with autistic people are outnumbered by people who can’t/don’t/won’t.
